so someone told me that there is a bundle of BLACKBERRY THEMES on the demonoid site?????if i get them will the all work on my 8320????? Also, i just put in a new 4GB micro in and my phone seems to be lagging for some reason.....any one know anything about this ?

Themes depend on what OS/device the themes were designed for. Read the specs for the themes and what OS's they work on.

The device can lag while the device scans the card. It should speed up after a while.

Just so you all know, demonoid is a torrent site with a lot of pirated stuff on it. These themes he's talking about are probably pirated premium themes.

Well that's not cool.
